Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings.
Referring to fig. 1, 2, 3 and 4, the invention provides a screw elevator, comprising a car 1, a bearing base 2 for bearing the car 1, a rotation control device for controlling the car 1 to rotate and a screw driving device for driving the bearing base 2 to ascend and descend;
the bearing base 2 comprises a bearing bottom plate 21 and a rotating disc 22 for bearing the car, and the car 1 is arranged on the rotating disc 22; the bearing base 2 is provided with a car groove 23 for installing the rotating disc, and the rotating disc 22 is provided with a fixing groove 221 matched with the shape of the bottom of the car 22.
The rotation control device comprises an equipment mounting plate 3, a driving gear 4 and a limiting part 5 for limiting the side turning of the car, and the car 1 is mounted between the equipment mounting plate 3 and a bearing bottom plate 21;
the top of car 1 is equipped with annular linkage portion 11, annular linkage portion 11 be equipped with drive gear engaged with rack 12, locating part 5 distribute in the outside of annular linkage portion 11, rack 12 is circular form.
Specifically, the screw driving device comprises a screw 6 and a main driving motor 9 for driving the screw 6 to rotate, the bearing bottom plate 21 and the equipment mounting plate 3 are both provided with a ball sleeve 61 matched with the screw 6, and the main driving motor 9 drives the screw 6 to rotate so as to enable the ball sleeve to move up and down along the screw, so that the bearing bottom plate 21 and the equipment mounting plate 3 can move up and down along the screw 6.
In order to improve the bearing capacity of the invention, at least 2 screw rods 6 are provided, and in order to ensure that each screw rod 6 can synchronously rotate, the screw rod driving device further comprises a screw rod gear 7 for driving the screw rods to rotate, a rotating shaft gear 71 and a transmission gear 72, wherein the rotating shaft gear 71 and the transmission gear 72 are installed on the main driving motor 9, the screw rod gear 7 is fixedly connected to the screw rods, and the screw rod gear 7 and the rotating shaft gear 71 are linked through the transmission gear 72. The rotating shaft gear 71 is mounted on the output shaft of the main driving motor 9, the rotating shaft gear 71 and the screw gear 7 are driven by the transmission gear 72, and a corresponding number of transmission gears 72 can be added according to the span of the car 1.
In terms of controlling the rotation angle of the car 1, the rotation control device further includes a first drive shaft 41 mounted on the equipment mounting plate 3 and a first motor 42 for driving the first drive shaft 41, and the drive gear 4 is mounted on the first drive shaft 41. Thus, the rotation of the car 1 can be controlled by the first motor 42.
Moreover, in order to better feed back the rotation condition of the car 1 to the first motor 42, one side of the limiting member 5 is provided with a rotation angle detector for detecting the rotation angle of the car 1, the rotation angle detector is provided with a detection roller 51 for detecting the rotation stroke of the annular linkage portion, and the detection roller 51 is attached to the side wall of the annular linkage portion 11. Therefore, when the car 1 rotates, the detection roller 51 is driven to rotate at the same time, and finally, the rotation angle of the car 1 can be measured according to the number of rotation turns of the detection roller 51 and the rotation radius of the annular linkage part 11, so that the first motor 42 can perform real-time rotation adjustment according to the actual rotation condition of the car 1.
Because the ball sleeve 61 on the equipment mounting plate 3 and the bearing base 2 can slightly move out of synchronization along with the longer service life and the influence of the splicing part between the screw rods, namely, the distance between the ball sleeves 61 can correspondingly generate the tendency of increasing or decreasing, the balls in the ball sleeves and the ball grooves for mounting the balls are damaged, and the service life is shortened. Therefore, the equipment mounting plate 3 and the bearing base 2 are separately and independently driven to lift so as to solve the problem. Meanwhile, in order to avoid the limitation that the annular linkage portion 11 is separated from the limiting member 5 due to an excessively large distance between the equipment mounting plate 3 and the bearing base 2, a push switch 52 for controlling the main driving motor 9 is arranged at the bottom of the limiting member 5, and the push switch 52 is pressed between the limiting member 5 and the top of the car 1, so that when the overlapping area between the limiting member 5 and the linkage annular portion 11 is reduced to a preset value, the push switch 52 can be completely bounced, so that the power supply of the main driving motor 9 is cut off, and the annular linkage portion 11 is prevented from being separated from the limiting member 5.
In order to prevent the situation that the car 1 cannot continue to rotate to the preset door opening direction due to power failure of the car in the rotating process, a second driving shaft 8 is installed on the equipment installation plate 3, and the second driving shaft 8 is provided with a standby driving gear 81 meshed with the rack 12. The bottom of the second driving shaft 8 is provided with a socket 82 for the external handle 9 to be connected and driven, and the car 1 is provided with a detachable access panel (not shown in the figure). Therefore, the invention can preset a handle 9 for manually rotating the second driving shaft 8 in the car 1, when the car 1 needs to be manually rotated in case of emergency, the access panel can be opened, the handle 9 preset in the car 1 is inserted into the inserting port, and then the second driving shaft 8 is slowly rotated, so that the car door of the car 1 can correspond to the landing door.
Rotating base 62 is installed to the bottom of screw rod 6, rotating base 62 is equipped with the mounting hole 621 that is used for screw rod 6 to insert, the bottom in the mounting hole 621 is equipped with the thrust bearing who is used for supporting screw rod 6.
While the foregoing is directed to the preferred embodiment of the present invention, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention.
